Christchurch residents now have a chance to see what the CBD's green frame and Avon Precinct will look like.

A 15-metre-by-12-metre 1:100 scale polystyrene model has been unveiled at the Air Force Museum at Wigram and will be on display until June 16.

The model, sponsored by Aurecon and Warren and Mahoney Architects, follows the guidelines as outlined in the Christchurch Central Development Unit's blueprint for the future make-up of the city centre.

Fifty-five students from New Zealand's four architectural schools, including Christchurch Polytechnic Institute of Technology, created the model after a four-week workshop and a month of designing as part of The Studio Christchurch Summer School.

Aurecon technical director Shaun Hardcastle said the aim of the model was to stimulate discussion about the future of Christchurch, particularly the green frame.

"We used a wasabi green for the model as being indicative of the way that wasabi stimulates and invigorates the senses. This is what we want to see happening to people's thinking."
